๐ Excited to welcome ๐๐ฎ๐ฟ๐ฟ๐ ๐ฆ๐ผ๐น๐ผ๐๐ฎ๐ (@harrysolovay) to ๐๐ณ๐ณ๐ฒ๐ฐ๐ ๐ ๐ถ๐ฎ๐บ๐ถ #๐ฏ!
I first discovered Harry through his incredible hardcore TypeScript tutorials on YouTube. His depth of knowledge, creativity, and ability to push the boundaries of the type system immediately stood out.

Harry is now building @crosshatchdev, an Effect-native toolkit for x402 payments, enabling applications and AI agents to seamlessly pay for and monetize APIs through programmable micropayments. Alongside projects like Liminal, his work continues to push the boundaries of whatโs possible with TypeScript and Effect.
Itโs a real privilege to have him share his ideas with the Miami developer community!

I am finding that anything in effect is just by default better than anything else. Agent just falls into a pit of success
๐ Excited to announce John De Goes @jdegoes as our main speaker for Effect Miami #3!
Itโs a real honor to welcome John, one of the most influential voices in modern functional programming. Creator of ZIO, founder of Ziverge, and Golem Cloud, his work has helped shape how we think about building reliable, composable software.
๐ค โHarnessing AI Models with Effect TSโ
Iโm particularly excited to hear Johnโs perspective on using Effect to build the next generation of AI-powered applications.
An incredible opportunity for the Miami developer community to learn from and connect with someone who has contributed so much to our ecosystem!

The @EffectTS_ LSP and Oxlint rules are now faster!
Couple of optimisations are in and now if you run the effect's lsp rules either in patched tsgo mode or in oxlint with typecheck: true, you should see at least a 15% improvement!
...and there's still some room for other optimisations that will come soon!

We're live again building with the CAFE stack - come hang out with @devinjameson , @samgoodwin89 and I while we nerd snipe one another

Been building an @EffectTS_ native ORM for a while, and it's finally ready for some of you to try.
- includes ClickHouse + Postgres
- Fully typesafe
- Migrations for both, and it can adopt your existing drizzle-kit migrations
Still early, but it's been running @Mapledotdev in production for about a month.

Built with Effect ๐ฅ
Introducing Expand Fetch, a new way to scrape and crawl the web.
Your agent has never seen the web. No wonder it gets basic questions wrong.
Traditional Markdown APIs lose critical details. So we trained two System one models to change that:
Iris, a vision model that sees pages like you do, preserving tables, icons, and layouts.
X-Ray, a JSON model that uncovers the hidden data behind every page.
Every fetch also comes with a Wayback Machine. Every line links back to its source, so you can verify exactly what your agent saw.
Three products. One API.
On our benchmark of 1,094 questions across 326 challenging web pages, agents using Expand got 74% right. The next best API got 55%.
Available today at $1 per 1,000 fetches.
Try it at expand.ai

Absolutely! And yes this wouldn't have been possible without Effect. Now gotta migrate to Effect 4! cc @MichaelArnaldi
